One thing I should correct from my previous post, which is very important, is that the 500metres down plunge doesn't mean 500metres vertical from surface.
The shallow angle that the Alexander River high-grade gold shoots run, is in a shallow diagonal direction down plunge. (Between the black lines)
Which makes it significantly easier and cheaper to mine than if it was vertical.
The advantage of this shallow diagonal angle is that you can mine 1,000metres of high grade gold quartz lode (1.128Million Oz worth today $A2.67Billion) and only be ~300-400metres from the surface, or 2,000metres (~2million Oz worth today $A4.9Billion) of high grade gold quartz lode and only be ~500-600metres from the surface.
With Alexander River, the Bruno Shoot runs for 500+metres at the surface before the Loftus Mackay Shoot west-dipping drops only 100metres from the surface. Highlighted in Yellow with blue border.
Siren Gold effectively has more than 1/2 a km of high-grade surface gold to mine at AR. (excluding the area at the top of AR between the Bruno Shoot and Bull Shoot.
This is exactly the same for Blackwater next door, and Fosterville in Victoria.
